1-Hydroxybenzotriazole → 7-(2-Fluoro-4-methylsulfanyl-phenylamino)-pyrrolo[1,2-c]pyrimidine-6-carboxylic acid (2-vinyloxy-ethoxy)-amide

Participants

Reaction Steps

7-(2-Fluoro-4-methylsulfanyl-phenylamino)-pyrrolo[1,2-c]pyrimidine-6-carboxylic acid (200 mg, 0.63 mmol), O-(2-vinyloxy-ethyl)-hydroxylamine (106 mg, 0.69 mmol), HOBt (94 mg, 0.69 mmol), EDCI hydrochloride (132 mg, 0.69 mmol) and DIPEA (118 μL, 0.69 mmol) were dissolved in DMF (5 mL). The reaction was stirred at room temperature for 16 hours then concentrated in vacuo. The resultant residue was dissolved in ethyl acetate (10 mL), washed with aqueous saturated sodium bicarbonate solution (10 mL) and the aqueous fraction extracted twice with ethyl acetate (2×10 mL). The combined organic fractions were washed with brine, dried (MgSO4) and concentrated in vacuo. The resultant residue was subjected to flash chromatography (SiO2, gradient 0-100% ethylacetate in cyclohexane) to yield the title compound as a brown solid (139 mg, 55%). LCMS (Method B): RT=3.35 min, M+H+=403.
